Abstract: Without electromagnetic stirring and normalizing annealing equipment for the production of high-grade non-oriented silicon steel, the bell furnace annealing equipment was used to produce highgrade 50BW350 non-oriented silicon steel products in BX Steel by formulating reasonable chemical composition and process system. The results showed that the produced 50BW350 non-oriented silicon steel meets the standard requirements with the magnetic induction of  1.70 T and iron loss of 3.1 W/kg, and the mass production of high-grade non-oriented silicon steel 50BW350 is successfully realized in BX Steel.
